The first incident happened just before 1am in the Marton area and ended when the car being tracked drove into a dead end.
Two men were arrested.
The chopper was scrambled again just before 5am, again to the Marton area, following reports of two stolen cars involved in a pursuit.
Both cars were abandoned and their occupants were arrested - one with assistance from the helicopter crew.
